The Gunung Mulu National Park in Borneo (near Miri) is a UNESCO World Heritage Site with caves and karst formations. The caves are home to over 5 million bats who exit the caves in search for food every evening in a spectacular way.

Melaka

Melaka (a.k.a. Malacca) is the capital of the Malaysian state of Malacca.
Traditionally, the spot where Melaka stands today was the center of Malaccan history. It was the capital of the Malaccan Sultanate and the center of the Malay world in the 15th and the 16th century before it fell to the Portuguese in 1511. Centuries of colonization by the Portuguese, Dutch and the British have shaped the architecture of the town.
